Cummins diesel generator does not generate the treatment method

First, the reasons why diesel generators do not generate electricity

1.Diode breakdown, not rectifier effect.

2. The brush is stuck in the brush holder, and the generator can not generate electricity because it is not excited.

3. The magnetic field coil of the rotor is not energized: the folded layer of the rotor coil is many, and some coils are not immersed in the bottom of the coil when the insulating paint is immersed, and the gap between the bottom coil turns and turns exists. As the engine speed changes, there will be different centrifugal forces in the bottom coil. Coil contraction, expansion frequency, diesel generator rental determines the number of coil and lead Angle size conversion, common magnetic field coil to slip ring lead, especially the lead of the bottom coil used for too long, will produce metal fatigue and broken.

4. Short-circuit or tie-in between stator coils.

5. The rotor claw is very loose: if in the shaft. A little loose, then the claw pole inner end face and the end face of the magnet will have a gap between the magnetic field coil generated flux will be missed in this, resulting in greatly reduced stator flux, stator coil induction of electromotive force is also greatly reduced, so that can not produce enough voltage to charge the battery.

Two, diesel vehicle generator does not generate power treatment method

1. Measure whether there is real electricity, the generator replacement voltmeter.

2. Set it to automatic or manual.

3. Check and correct according to the circuit diagram.

4. New generators or machines that are not used for a long time appear easily. You can press the charging button on the control panel for magnetization, or you can use 12V battery to magnetization the excitation winding, and the positive pole is connected to F1, and the negative pole is connected to F2. If the voltage can not be established, the battery positive and negative electrode exchange again.

5. Clean the ring surface, sand the carbon brush end face to make it and collector ring surface arc anastomotic area is greater than 70%, strengthen the spring pressure.

6. Clean the carbon brush and the carbon brush grip so that the carbon brush can move freely.

7. Use a multimeter to check the diode positive and negative resistance, such as damaged replacement.

8. Check with a multimeter, if the positive and negative resistance does not meet the requirements of diode characteristics when replaced.

9. The generator set with a multimeter 1K check winding, if the resistance value is infinite, should be connected. Check again with 1 ohm. If the resistance value is zero, replace or treat the windings. If not, check whether the connector is loose.

Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
